11. Design and Construction of a Multi-Port Beamsplitter Based on Few-Mode-Fibers
University essay from Linköpings universitet/InformationskodningAbstract : A MBS (Multi-port beamsplitter) for higher dimensional quantum communication has been designed and constructed and the theory and method for this is presented in this thesis. It uses optical fibers in a heterogeneous structure with a single-mode fiber spliced to a multi-mode fiber and then spliced to a few-mode fiber. READ MORE

12. Theoretical and experimental investigation of themagneto-optical eect in graphene in the THz region
University essay from Uppsala universitet/FREIAAbstract : In many optics applications we need lenses with dynamically tunable focal lengths. One design of such a lensis developed in and it relies on the magneto-optical eect. In this design, a graphene layer is placed ina magnetic eld that varies quadratically in space. READ MORE

13. Magnetically tunable microwave resonator/filter
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : The magnetic tunability of ferrites has been studied and applied on many electric components for working in various frequency bands. Filters or resonators loaded by ferrites can thus work for different frequency requirements by tunning external biasing field. However, filters or resonators built by traditional waveguides are large in size. READ MORE

14. ELECTRONIC STRUCTURE AND THERMODYNAMIC PROPERTIES OF LI-IONINSERTION IN SULFONAMIDES COMPOUNDS AS ORGANIC HIGH-ENERGY DENSITY CATHODES
University essay from Uppsala universitet/Materialteori; Uppsala universitet/KärnfysikAbstract : The world’s ever-growing energy demand has evoked great interest in exploring renewable energy sources along with sustainable energy storage systems. While inorganic physics of rocking chair mechanism used in Li-ion battery have proven to provide high energy density and high performance, there are problems yet to be overcome in terms of sustainability and recyclability.

15. Functionalization of nanofibrillated cellulose with the host defense peptide KR-12
University essay from Uppsala universitet/Nanoteknologi och funktionella materialAbstract : When the process of wound healing is disturbed, chronic wounds may develop. Chronic wounds heal very slowly over long periods of time, and require specialised care in order to prevent further infection. This causes considerable suffering to the patient and increased healthcare costs. READ MORE
